DHP HM resin (100-200 mesh)

Descrição detalhada : A highly versatile support for the solid phase immobilization of primary, secondary alcohols [1-11], phenols [12], purines [13], and indoles [14]. Derivatization is effected by treating the support in DCM with an excess of alcohol in the presence of a catalytic amount of pyridinium p-toluenesulfonate. A similar DHP-based support has also been used for the immobilization of tetrazoles [15].Release of the product alcohol from the support has been carried out by treating with 95% TFA/5% water [1] and TFA/DCM/EtOH [2, 12]. However, the use of TFA can lead, in some cases, to trifluoroacetate formation. Methods which eliminate this potential side reaction include PPTS/BuOH/DCE [3], TosOH in DCM [16] and TosOH in DCE/BuOH [17]. The product number for this product was previously 01-64-0192.To obtain a certificate of analysis (CoA) of a lot that begins with the letter "A", please select the option in the right hand menu "Request a COA for Lot#s starting with A".
